NCBI ROFL: Murder: an evolutionary adaptation?

The homicidol effect: investigating murder as a fitness signal.

"This article extends homicide adaptation theory by investigating signal effects of a murder. In two experiments (N = 299 and N = 161) participants reported their perceptions of a described person. The first study manipulated the information about the person (including or excluding a single sentence stating that the person has committed a murder) and stimulus person/observer sex match (same vs. opposite sex). Results suggest that murder functions as a signal of the described person's fitness that enhances observers' evaluations and inclination to interact with the person. Opposite-sex observers evaluate the murderer's intent more favorably than same-sex observers, but these evaluations of intent produce differential (positive vs. negative) effects between the two groups. The second study replicated the findings and ruled out potential confounds."

Homicide victim found at vacant Everett house

EVERETT -- Police on Wednesday were canvassing the View Ridge-Madison neighborhood in Everett after a man was found dead there the night before. A neighbor spotted the man on the ground outside a vacant house at 22 Madison St. He called 911 about 6:20 p.m. The man had obvious signs of trauma to his torso, police said. He looked to be in his late 20s or early 30s. The Everett Major Crimes Unit is investigating the death as a homicide, Lt. Robert Goetz said. Detectives declined to say more about how they believe the man may have died. There are no identified suspects or motives. Detectives received a search warrant around 11:45 p.m. Tuesday and collected evidence at the scene. They returned Wednesday afternoon to look for clues in the daylight, Goetz said. The victim's identity had not been determined as of late Wednesday afternoon. The body was turned over to the Snohomish County Medical Examiner's Office. Anyone with information is asked to call 425-257-8450. Rikki King: 425-

Manslaughter charges possible in boy's death

Published: Thursday, August 23, 2012, 5:55 p.m. MONROE -- Detectives believe a 7-year-old Monroe boy's parents should face second-degree manslaughter charges in connection with his January overdose death. Monroe police this week wrapped up their probe into the boy's Jan. 30 death and forwarded the case to prosecutors to decide if his parents should face criminal charges. Snohomish County deputy prosecutor Lisa Paul likely will begin reviewing the case in the coming days. She doesn't expect to make a charging decision in the near future, however. "It's quite an extensive investigation, and I want to review it thoroughly before I make any decision," she said. The boy, identified as "A.J." in court papers, ingested a lethal amount of salicylates, a chemical common in aspirin and other over-the-counter drugs. The medical examiner declined to conduct an autopsy on the boy, making it difficult to determine how the drug ended up in the boy's system. A
